LOOM FOR WEAVING DOUBLE PILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 414,647, dated November 5, 1889. Application filed April 5, 1888. Serial No. 269,681- (No model.) Patented in England August 21, 1885, No. 9,918.

Crreat Britain, dated August 21, 1885, No.

9,918), of which the .following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

. Our inven tion relates to looms for weaving double pile fabrics, in which two or more cloths or backin gs are simultaneously woven with connecting pile threads between them and out apart laterally, so as to form two separate pieces of pile fabric delivered simul-.

taneously at the front of the loom and our improvements relate to that portion of the loom which controls the weaving of the connecting pile-threads forming the pile surface of the plush or fabric produced.

It consists in the mechanism hereinafter described for simultaneously connecting and simultaneously disconnecting the tappets or cams actuating the healds carrying the pile warp when in the process of weaving double pile fabrics it becomes necessary to weave a tab or plain piece of cloth without pile.

In the accompanying drawings, illustrating our invention, Figures 1 and 2 represent a section and side view, respectively, of the set of tappets employed, showing the devices for connecting and disconnecting it with the tappet-shaft, the tappets actuating the healds carrying the pile warp.

The construction and operation of the frame-work and leading features of a doublepile-plush loom are well known in the art, and it is therefore unnecessary to illustrate or describe the same; but for greater certainty reference maybe made to English Letters Patent to George Davies, No. 2,429, dated November 1, 1858, for the general features of such a loom.

Our invention is applied to that portion of the loom known as the shedding mechanism, which is also well known in the art and unnecessary to show or describe; but for greater certainty reference may be made to our said English patent above referred to, No. 9,918, of August 21, 1885; and to United States Letters Patent No. 292,664, dated J anuary 29, 1884, in the drawings of which is shown a loom for weaving double pile fabrics having shedding devices, the general features of which are such as are in common use,.and which may be employed in connection with the tappet-cam mechanism forming the subject of our present invention. It is to be noted, however, that such features of the loom shown in said English Patent No. 2,429, of November 1, 1858, and United States Patent No. 292,664, of January 29, 1884, as are necessary to be used in connection with the present improvements to operate it are common to all looms for weaving double pile fabrics, reference being made herein to such patents merely for the purpose of illustration, in order that our present invention and its application to a doublepile-plush loom may be clearly understood.

Referring now to Figs. 1 and 2 of the annexed drawings, wherein is specifically shown the improvement constituting the subject? matter of our present invention, A is the tappet or cam-shaft, shown broken off and disconnected from the loom. The driving mechanism intermediate between it and the main shaft, being that ordinarily employed, is 85 therefore not shown.

B is asleeve fixed on the shaft A by the set-screws C or other known analogous detachable or disconnectible means. The tappets or cams D are employed to actuate the healds carrying the pile warps and are made to fit the sleeve 13*, being aflixed to said sleeve by the set-screws E and bolted together by the bolts F while the tappets (l are annexed to the tappet-shaft A in the 95 usual manner. Thus when in weaving double pile plush on the loom it is required to weave a tab or plain piece of cloth without pile it is only necessary to loosen the set=screws C and the tappet-shaft A? then revolves, leav- Ice tappet-cams Diemployed to actuate the wai p healds adj ustably secured to the sleeve 15 13?, and the tappets G2, secured to said tappetshaft A substantially as and for the purpose set forth.

In testimony whereof. we have hereunto affixed our signatures this 9th day of Deceln- 20 her, A. n. 1885.
